It wasn’t uncommon for boys to lie about their age in order to serve. Ray Jackson, who joined the Marines at 16 during World War II, founded the group Veterans of Underage Military Service in 1991, and it listed more than 1,200 active members, including 26 women.

@ Seantaclaus: Add to that the Flynn Effect and IQ scores become even more of a crock.

As for the high-IQ, circle-jerk club which calls itself Mensa - I so hope this is true - originally, they were going to call themselves "Mens", based on the latin for "mind", until someone pointed out that name might attract a totally different special interest group. So they went with "Mensa" instead, meaning "table"; an apparently irony-free way of representing how they "come together in a round-table meeting of equals."
